Nothing new here

Getting strong and fit is no secret.  Your ancestors knew how to do it, but nowadays it's all smoke and mirrors, adverts, endorsements and false promises.  It's a billion dollar industry that consists of reinventing the wheel. Work hard, pick up heavy stuff and move it. That's what you need to do. Look at everything Arnie ever wrote - bench press, squat, overhead press and deadlift.  What tends to happen in traditional gyms is that most people feel the need to fill their workouts with stuff that won't yield results. Go to the gym, do some full depth, heavy squats and then guess what?  Get home, eat and sleep.  You don't need to be working calve raises or leg extensions yet.  Master the basic 'macro' strength moves before you try and specialise in the more localised areas of the body. Can you squat heavy? Are your legs bursting out their skin?  If the answer is no, and you aren't at that level, then you don't need to waste your time the other leg machines. Practice your squats. Get your form in order. Get to where you can do a full deep squat below parallel, then build up the weight slowly. For clarity here, you will know if this piece is aimed at you.  I know plenty of people that train who do need to do all the ancillary lifts to keep their already established physiques, but most gyms are bursting at the seams with people who don't.  

Health publications do little to help and educate.  If they did then they wouldn't really be in business. If you are looking for some advice on hard work then check out CT Fletcher on YouTube.  Check out his work ethic and what he says about training hard. You don't need fancy kit, you just need the basics.  Look at the CrossFit idea - squat, deadlift, press - it's all the same thing.  Now, if you want to add a conditioning element then CrossFit is good for you.  If you want to be a bodybuilder your conditioning will follow a different model.  Again, if you are a power lifter then is conditioning a massive part of what you need?  What you want to do is the see the commonalities and just work hard on the basics.  Build a solid foundation and you can't go wrong.
